There is a problem with average computing in aggregation. RoundingMode is missing.
Once this is fixed we need to check how to handle that rounding errors are not propagated etc.

Rounding in aggregation is now done using MathContext.DECIMAL32 and stripTrailingZeros(). This avoids rounding errors when computing average. stripTrailingZeros() may sometimes reduce precision more then it should by it avoids having always a precision=7 once there was a single computation step that resulted in a rounding issue.
As average is not an important parameter for aggregation this should be sufficient.
